Balsa Model Assembly Jig

<p>The larger slotted one provides a way to hold 3/32" thick balsa or plywood pieces squarely for joining. The second narrower slotted one is for 1/16" thick pieces. The tall ones help align curved or slanted keels.</p> <p>Each slotted piece attaches to the rail with a Tee nut that's threaded M4. Threads are crap and need to be chased with a tap. Slotted pieces on top are good to go as is.</p> <p>Each assembly is held together and in place by an M4 x 12mm socket head cap screw.</p> <p>Each leg assembly is held in place with either M4 x 8mm set screws or socket head cap screws.</p> <p>Align the slot on the bottom of the fixtures with the protruding part of the Tee nut to ensure accuracy.</p> <p>Pieces attach to a 20x20mm section of 80/20; the longer the better!</p> <p>Minimum distance between two parallel slots is 1" but it can be reduced to 3/4" by nipping off the ends of the Tee nuts.</p> <p>No support is needed if printed as shown.</p> <p>I use them for building model boats and planes to keep ribs square to the keel while glue dries.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Ender 3</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>Doesn't Matter</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p><strong>Filament:</strong></p> Hatchbox PLA <p>Any</p> </p> Category: Hobby
